Submission + - Boeing 777 parts wash up on Reunion Island - what are the odds from MH370?

garyisabusyguy writes: According to this CNN article, the part numbers on the washed up airplane parts correspond to a Boeing 777.

Given that no other 777 's have crashed into the Indian Ocean, and that the Indian Ocean Gyre would move wreckage from the West coast of Australia towards Africa...

Some questions come to mind:
1. What are the odds that this is wreckage from MH370?
2. Is there any other reason that people would be dumping 777 parts into the Indian Ocean?
3. If it is from MH370, can analysis of the Gyre provide additional insight into the location of the crash?
4. What are the tools that can be used to analyze the currents of the Gyre, and how accurate are they?

Submission + - Elon Musk offers explanation for loss of Falcon 9 mission

garyisabusyguy writes: This Forbes article provides the best analysis of the loss of the last Falcon 9 mission based on information released by Elon Musk.
Highlights:
1. Sound triangulation led them to identify a strut holding helium tank as root cause where the falling helium tank pinched a line causing overpressure in the LOX tank.
2. The failure occurred at 2,000 pounds of force, and the struts were rated at 10,000 pounds of force. They initially dismissed this as a cause until sounds triangulation pointed back to the strut
3. Further testing of struts in stock found one that failed at 2,000 pounds of force, with further analysis identifying poor grain structure in the metal, which caused weakness
4. It will be months before the next launch while SpaceX goes over procurement and QA processes all struts and bolts, and re-assesses any "near misses" with Air Force and NASA
5. Next launch will include failure mode software, which will allow recovery of the Dragon module during loss of the launch vehicle since they determined that it could have saved the Dragon module in this lost mission

I'm still waiting for them to stick the landing,which could be a way in the future

Submission + - Yet another study suggests that Sixth Extinction Event is underway

garyisabusyguy writes: This is not the first time that it has been proposed that an extinction event is underway. However, this new study takes into consideration many other factors that may be tilting the data, and still come up with the inevitable conclusion that we have triggered a large die-off, and that we may become victims of it as well.

From the paper summary:
"Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 114 times higher than the background rate. Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear. These estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already "

But wait, the authors suggest that rapid work to avert the worst of the die-off is still possible. The question may really be whether we can get past paid trolls, fud and finger pointing in order to act wisely in a timely manner.

Submission + - Russia and China crack encrypted Snowden files. Britain responds

garyisabusyguy writes: According to Sunday Times:
RUSSIA and China have cracked the top-secret cache of files stolen by the fugitive US whistleblower Edward Snowden, forcing MI6 to pull agents out of live operations in hostile countries, according to senior officials in Downing Street, the Home Office and the security services.

And this non-paywalled Reuters version:
http://www.reuters.com/article...

MI6 has decided that it is too dangerous to operate in Russia or China. This removes intelligence capabilities that have existed throughout the Cold War, and which may have helped to prevent a 'hot' nuclear war.

Have the actions of Snowden, and, apparently, the use of weak encryption, made the world less safe?

Submission + - Rand Paul annouces for presidental primary but...

An anonymous reader writes: Rand has announced for the US presidential primary, but his announcement video is not viewable in this country
http://www.buzzfeed.com/kylebl...

He gives photos of people across the country endorsing him, but the people are all stock photos from a European photographer
http://www.buzzfeed.com/andrew...

This raises two questions...
1. Should politicians in America be expected to use American resources?
2. Does Buzzfeed always beat /. to the punch?

Submission + - Bitcoin implementation problems and exposure to fleecing (rt.com)

An anonymous reader writes: Well, it looks like the new version of Silk Road has had problems with their implementation of bitcoin and as a result a few million dollars of user bitcoins has disappeared
Is this an acceptable hazard of a grey marketplace, or do user have legal recourse to reclaim their lost funds?
FTA:
“Without competition the wisest thing to do is to shut down the market, doing it in a timely and orderly manner,” wrote one administrator without mentioning an expected return date. “We will be back up. But to speed up we need to close shop. Don't worry, we don't rip [off] anyone and will be back stronger than ever.”
